[webbeans-issues] [JBoss JIRA] Updated: (WBRI-193) resolve potential LinkageError

resolve potential LinkageError ------------------------------ Key: WBRI-193 URL: https://jira.jboss.org/jira/browse/WBRI-193 Project: Web Beans Issue Type: Patch Affects Versions: 1.0.0.BETA1 Reporter: Takeshi Kondo Priority: Trivial Attachments: Proxies.java.patch Some time age, LinkageError is caused by Seam's Javassist ProxyFactory usage. It same applies to WebBeans. if possible, make a modification from --- ProxyFactory proxyFactory = new ProxyFactory(); proxyFactory.setSuperclass(getSuperClass(); proxyFactory.setInterfaces(getInterfaces()); return proxyFactory; to --- ProxyFactory proxyFactory = new ProxyFactory(); Class<?> superClass = getSuperClass(); if(superClass != Object.class) { proxyFactory.setSuperclass(superClass); } proxyFactory.setInterfaces(getInterfaces()); return proxyFactory; --- Apply to this patch, If proxy target class is interface, generated proxy class name changes form "org.javassist.tmp.java.lang.Object_$$_javassist_0" to "org.javassist.tmp.java.util.List_$$_javassist_0". All interface generated proxy class name is "org.javassist.tmp.java.lang.Object_$$_javassist_(number)" Because proxy class name pattern is monotone, duplicate proxy class name, then it causes LinkageError.
